Double Countertop Water Filter For High Sediment 1 Micron Replacement Set KDF & Sediment Filter
Lower concern product; no known PFAS use in standard filter media.
KDF and sediment filter cartridges typically contain copper-zinc alloy and cellulose or polypropylene without intentional PFAS. LG makes no PFAS claims; standard water filter media poses minimal PFAS risk.

The full breakdown
What it's made of and why it matters
This filter uses KDF-55 media (copper-zinc alloy) and a 1-micron sediment cartridge as the mechanical filtration stages. KDF is a well-established, chemically stable medium that does not leach into water under normal use and works by reduction-oxidation reactions to reduce chlorine and heavy metals. The sediment cartridge is typically polypropylene or cellulose-based and poses no known chemical leaching risk when kept dry and replaced on schedule. The housing material is not specified in available product information; LG typically uses polystyrene or polyethylene for countertop filters, both chemically inert for cold water contact.
The brand's record and disclosure
LG does not publicly disclose detailed safety testing or third-party certifications (NSF, WQA) for this specific model in widely accessible sources. The brand has not faced documented recalls or safety controversies specific to this countertop filter line. LG's water filtration division operates with minimal public transparency on material sourcing and chemical compliance; no known misrepresentations have been established, but independent verification is limited.
How it compares in its category
Countertop sediment and KDF filters are among the lowest-risk water treatment products available; they contain no electrical components, no ion-exchange resins that can degrade, and no activated carbon (which can support bacterial growth if saturated). This product's two-stage design is typical and appropriate for high-sediment water. Most competitors in this price segment use identical media types and offer similar hazard profiles, though some market brands (Brita, PUR) provide more detailed NSF certification documentation.
If you buy it
Replace cartridges every 3 to 6 months depending on water sediment load; LG does not specify flow rate decline as a replacement trigger, so follow the manufacturer's printed schedule. Store the filter in a cool, dry location away from direct sunlight to prevent housing brittleness. Rinse the sediment cartridge housing with tap water before insertion to avoid trapped particles. Do not use this filter for untreated well water without prior microbial testing, as the sediment stage alone will not remove bacteria or viruses.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Bacterial growth in cartridge
If cartridge is not replaced on schedule or if filter housing sits unused for extended periods, stagnant water can support microbial colonization. This is a maintenance issue, not a material defect, and is mitigated by regular replacement.
KDF media fragmentation or release
KDF-55 is mechanically stable and does not fragment under normal water pressure in countertop systems. No established cases of KDF particle release into treated water have been documented for this product category.
Housing material leaching
Polystyrene or polyethylene housings do not leach chemical additives into cold water under typical countertop conditions. No BPA or phthalate hazard is established for this application, though housing material is not officially confirmed for this model.
Sediment cartridge structural failure
Over-pressurization or physical damage can rupture the sediment cartridge, allowing bypassed sediment into treated water. This is a wear issue; cartridge replacement is the preventive control.
Chlorine residue in treated water
KDF media is designed to reduce chlorine; complete removal is not guaranteed, especially as cartridge ages. Residual chlorine is a taste issue, not a safety hazard at EPA-regulated tap water levels.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
